Werner's syndrome associated with scleroderma-like syndrome: case report and literature revision
Werner's syndrome is a rare autosomal recessive disease associated with premature ageing. Skin alteration must be distinguished from cutaneous manifestation of systemic sclerosis (SSc). We describe a case of a 39 years old patient with Werner's syndrome admitted with an initial diagnostic hypothesis of SSc. The patient had many characteristic features associated with Werner's syndrome including gray hair, hoarseness, short stature, scleroderma-like skin changes, diabetes mellitus, cataracts, hypogonadism, hypothyroidism, and hyperlipidemia. There was no Raynaud's phenomenon, other typical visceral manifestation of SSc, nailfold capillary alterations or autoantibodies. Werner's syndrome diagnosis notwithstanding rare, should be remember in the differential diagnosis of SSc, mainly in the presence of atypical manifestations and in the absence of typical features of SSc.A síndrome de Werner é uma doença autossômica recessiva rara associada a envelhecimento precoce, cujo quadro cutâneo deve ser distinguido daquele encontrado na esclerose sistêmica (ES). Descrevemos aqui o caso de uma paciente de 39 anos de idade, portadora de síndrome de Werner, encaminhada ao nosso serviço com hipótese diagnóstica inicial de ES. A paciente apresentava várias manifestações associadas à síndrome de Werner, incluindo cabelos precocemente grisalhos, voz estridente, baixa estatura, alterações cutâneas esclerodermiformes, diabetes melito, catarata, hipogonadismo, hipotireoidismo e hiperlipidemia. Não apresentava fenômeno de Raynaud, manifestações viscerais típicas da ES, alterações capilaroscópicas periungueais ou auto-anticorpos. O diagnóstico de síndrome de Werner, apesar de raro, deve ser lembrado no diagnóstico diferencial de ES, principalmente na presença de manifestações atípicas e na ausência de alterações típicas da ES.UNIFESP-EPMAmbulatório de Doenças do Espectro da Esclerose SistêmicaUNIFESP, EPMSciEL

Behcet disease (BD) and BD-like clinical phenotypes : NF-kappa B pathway in mucosal ulcerating diseases
Behcet's disease (BD) is a heterogeneous multi-organ disorder in search of a unified pathophysiological theory and classification. The disease frequently has overlapping features resembling other disease clusters, such as vasculitides, spondyloarthritides and thrombophilias with similar genetic risk variants, namelyHLA-B*51,ERAP1,IL-10,IL-23R. Many of the BD manifestations, such as unprovoked recurrent episodes of inflammation and increased expression of IL-1, IL-6 and TNF alpha, overlap with those of the hereditary monogenic autoinflammatory syndromes, positioning BD at the crossroads between autoimmune and autoinflammatory syndromes. BD-like disease associates with various inborn errors of immunity, including familial Mediterranean fever, conditions related to dysregulated NF-kappa B activation (egTNFAIP3,NFKB1,OTULIN,RELA,IKBKG) and either constitutional trisomy 8 or acquired trisomy 8 in myelodysplastic syndromes. We review here the recent advances in the immunopathology of BD, BD-like diseases and the NF-kappa B pathway suggesting new elements in the elusive BD etiopathogenesis.Peer reviewe
Prevalence of intestinal nematodes in alcoholic patients
We report the results of a retrospective study on the frequency of intestinal nematodes among 198 alcoholic and 440 nonalcoholic patients at the University Hospital Cassiano Antonio Moraes in Vitória, ES, Brazil. The control sample included 194 nonalcoholic patients matched according to age, sex and neighborhood and a random sample of 296 adults admitted at the same hospital. Stool examination by sedimentation method (three samples) was performed in all patients. There was a significantly higher frequency of intestinal nematodes in alcoholics than in controls (35.3% and 19.2%, respectively), due to a higher frequency of Strongyloides stercoralis (21.7% and 4.1%, respectively). Disregarding this parasite, the frequency of the other nematodes was similar in both groups. The higher frequency of S. stercoralis infection in alcoholics could be explained by immune modulation and/or by some alteration in corticosteroid metabolism induced by chronic ethanol ingestion. Corticosteroid metabolites would mimic the worm ecdisteroids, that would in turn increase the fecundity of females in duodenum and survival of larvae. Consequently, the higher frequency of Strongyloides larvae in stool of alcoholics does not necessarily reflect an increased frequency of infection rate, but only an increased chance to present a positive stool examination using sedimentation methods
